基于STM32的家用安防控制系统设计

摘要如今，如果不及时发现室内事故，很可能会造成严重的人员伤亡，例如火灾、有毒气体、房屋漏水等，它会对内部造成很大的损坏。为了防止此类事件的发生，基于STM32的智能室内报警系统非常重要。近年来，不时报道多起室内灾害。例如，因煤气泄漏引起的火灾、中毒事件已达290多起，盗窃事件达350多起。其中86%是人为疏忽造成的，可见内部智能的开发设计还有很大的提升空间。随着室内报警系统的发展，室内火灾的发生率下降了60%，入室盗窃的发生率下降了70%。家庭报警系统在其中起着极其重要的作用。本课题基于STM32F103C8T6单片机设计了一套家用安防系统。该系统主要包括防火模块、防盗模块、蓝牙模块、摄像头探查系统等部分。设计工作分为硬件设计和软件设计两部分。在硬件设计中，采用STM32F103C8T6作为系统的MCU,MQ-2烟雾传感器和DHT11温湿传感器作为防火模块，热释电人体红外传感器作为防盗模块，HC-05蓝牙模块可以实时查看家庭情况并设置报警区间，通过ESP32-CAM搭载的摄像头可以远程查看家庭状态，保证户主及时查看家庭状态。根据上述硬件的各功能模块，分别进行了相应的软件设计。测试结果表明，该设计能够完全实现预期的功能目标。关键词：STM32单片机；防火防盗；红外传感器：DHT11;MQ-2:蓝牙ABSTRACTNowadays,if indoor accidents are not detected in time,it is likely to cause seriouscasualties,such as fire,toxic gas,house water leakage,etc.,which will cause great damageto the interior.In order to prevent such incidents from happening,a smart indoor alarmsystem based on STM32 is very important.In recent years,many indoor disasters have beenreported from time to time.For example,there have been more than 290 fire and poisoningincidents caused by gas leakage,and more than 350 theft incidents.Among them,86%arecaused by human negligence,which shows that there is still a lot of room for improvementin the development and design of internal intelligence.With the development of indooralarm systems,the incidence of indoor fires has dropped by 60%,and the incidence ofburglaries has dropped by 70%.Home alarm systems play an extremely important role inthis.This topic designs a home security system based on the STM32F103C8T6microcontroller.The system mainly includes fire protection module,anti-theft module,bluetooth module,camera detection system and other parts.The design work is divided into two parts:hardware design and software design.In thehardware design,STM32F103C8T6 is used as the MCU of the system,MQ-2 smoke sensorand DHT11 temperature and humidity sensor are used as the fire protection module,pyroelectric human body infrared sensor is used as the anti-theft module,and the HC-05Bluetooth module can check the family situation in real time and set the alarm interval,Through the camera equipped with ESP32-CAM,the family status can be checked remotelyto ensure that the head of the household can check the status of the family in time.According to each functional module of the above-mentioned hardware,the correspondingsoftware is designed respectively.The test results show that the design can fully realize theexpected functional goals.Key words:STM32 single-chip microcomputer;fire prevention and anti-theft;infraredsensor;DHT11;MQ-2;bluetooth目录摘要……………………………………………………IAbstract………………第1章绪论1.1课题研究目的及意义…1.2国内外研究现状…1.2.1国外研究现状1.2.2国内研究现状.21.3本设计研究主要内容…。3第2章方案的整体设计…2.1整体的方案设计…2.2器件的选型..52.2.1单片机的选取….52.2.2对射式红外传感器..62.2.3温湿度传感器.72.2.4烟雾传感器……82.2.5蓝牙模块..92.2.6摄像头模块的选择102.2.7显示模块.112.2.8报警模块..122.3本章小结.13第3章硬件设计....143.1主控STM32F103C8T6单片机.143.2显示模块电路的设计.153.3报警模块电路的设计…163.4蓝牙模块电路的设计…173.5检测模块电路的设计.18
